Wouldnt you need to grind two sets of cutters for the spindle moulder ? I thought the 80mm super block was the biggest you could get , but your probably going to prove me wrong :lol:
I've not heard of scratch stocks , but they sound fun
In principle, to be legal, yes I would - cutters and limiters (repeated for each block in stacked tooling) - unless you have a
throughfeed moulder (and no, I don't). There is, however, a British cutterblock system called the Armadillo which obviates the need to do this and yet provides the necessary limitation feature. It comprises a series of different sized rings bored for locator pins which assemble together into a cutterblock. Sadly I don't have one of those, either - although it is on the wish list. There are also a limited number of thicknessers which allow the use of profile cutters, but they're a bit rare these days.
The biggest cutter blocks I've seen are the 100mm high
Whitehill blocks, although if you go to serrated-back blades you can get blocks up to 150mm high (Garniga, etc) - however that takes a really heavy spindle moulder to run (not to mention a considerable amount of operator bravery, I'd say). If I wanted to do this in one pass then I'd consider using stacked tooling: a ready-made block/cutterset to form part of the profile with the "bespoke" bit on a second block above or below that on the spindle. Looking at my own tooling I'd actually prefer to make 3 passes - pass 1: large cove cut, pass 2: ogee-like bit on panel raiser, pass 3: nosing.
For the really technically minded Thermwood (CNC routers) have a software package called eCabinets which allows you to create your own profiles which the CNC then cuts in multiple passes using ball nose and straight cutters. All you need is the cutters - oh, and £90k worth of CNC router.......
And I knew Alf would get in with the scratch stocks reference..... :lol:
